lib/htmlcomponents: use relative links for the top page and for favicon.ico

This allows hiding VictoriaMetrics components behind proxies with arbitrary path prefixes.
For example, vmagent HTTP handlers can be served via /vmagent/ path prefix:

- http://proxy/vmagent/targets
- http://proxy/vmagent/service-discovery

The path prefix can be arbitrary. For example, below are vmagent urls
for /tenantID/vmagent/ path prefix:

- http://proxy/tenantID/vmagent/targets
- http://proxy/tenantID/vmagent/service-discovery

While at it, consistently serve favicon.ico from any path directory.

* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly parse `ca`, `cert` and `key` options at `tls_config` section inside [http client settings](https://docs.victoriametrics.com/sd_configs.html#http-api-client-options). Previously string values couldn't be parsed for these options, since the parser was mistakenly expecting a list of `uint8` values instead.
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): properly drop samples if `-streamAggr.dropInput` command-line flag is set and `-remoteWrite.streamAggr.config` contains an empty file. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5207).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): do not print redundant error logs when failed to scrape consul or nomad target. See [this pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5239).
* BUGFIX: [vmagent](https://docs.victoriametrics.com/vmagent.html): generate proper link to the main page and to `favicon.ico` at http pages served by `vmagent` such as `/targets` or `/service-discovery` when `vmagent` sits behind an http proxy with custom http path prefixes. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5306).
* BUGFIX: [vmstorage](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): prevent deleted series to be searchable via `/api/v1/series` API if they were re-ingested with staleness markers. This situation could happen if user deletes the series from the target and from VM, and then vmagent sends stale markers for absent series. Thanks to @ilyatrefilov for the [issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5069) and [pull request](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/5174).
* BUGFIX: [vmstorage](https://docs.victoriametrics.com/Cluster-VictoriaMetrics.html): log warning about switching to ReadOnly mode only on state change. Before, vmstorage would log this warning every 1s. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5159) for details.
* BUGFIX: [vmauth](https://docs.victoriametrics.com/vmauth.html): show browser authorization window for unauthorized requests to unsupported paths if the `unauthorized_user` section is specified. This allows properly authorizing the user. See [this issue](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5236) for details.
